function palindrome(str) {
// Good luck!
str.replace (str.toLowercase());
var array = str.split("");
array=array.reverse();
var string=array.join("");

if(str==string)
{ return true;}
else {
return false;
}

}

palindrome(“eye”);

what’s wrong with my code? please can someone help me out?

String.replace() doesn’t work the way you’re trying to use it, but you’ve got the right idea elsewhere. Try method chaining:

var newString = str.toLowerCase().split("").reverse().join("")
